MULTIPLE-PRINTING PRESS.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed June 21, 1906. Serial No. 322,667.

To all whom it 'may concern:

Be it known that I, AUGUST SCHEUERER, Jr., a citizen of the UnitedStates, and residing at Hoboken, in the county of Hudson and State ofNew Jersey, have invented certain new and useful Improvements inl\lultiple-Printin(r Presses, of which the following is a specication,such as will enable those skilled in the art to which it appertains tomake and use the same.

This invention relates to multiple-color printing machines, and theobject thereof is to provide a machine of this class with means wherebya series of different colors cart be applied successively to thematerial which is to be printed upon in order to obtain the finisheddesign or representation by a series of overlying tints of differentcolors; another object being to apply different tints of the same colorsimultaneously to a number of sheets to be rinted upon at eachrevolution of the orm cylinder; another object being to provide meanswhereby the adjustment of the separate and most essential members of theprinting press is facilitated and whereby also the inking mechanism as awhole can be entirely separated from the rest of the printing machine.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvements are designated by suitable reference characters ineach of the views, and in which Figure 1 represents a side View of myimproved machine; Fig. 2 a longitudinal vertical section of the same;Fig. 3 an end view of the same; Fig. 4 a detail sectional View of a partof the inking mechanism; and, Fig. 5 a section on the line 5-5 of Fig.4. Fig. 6 is a partial view showing details of construction.

In the drawings 1 is the main frame which supports the form-cylinder 2,the transfer cylinder 3, the paper cylinder 4, the paper roll 5, papertension 6 and various other adjuncts more specifically referred tobelow. The shaft 7 of the form-cylinder 2 rests in solid bearings whichform part of the main frame 1. The shaft 8 of the transfer cylinder 3rests in vertically adjustable bearings 9 which can be operated andregulated by means of the hand operated worm gear 10 and which willfacilitate the necessary alinement of the cylinder 3 superimposed uponthe cylinders 2 and 4. The shaft -11 of the paper cylinder 4 rests inhorizontally adjustable bearings 12 which consist of the usual brassesand followers with adjusting screws 13 well known in the art. The inkingmechanism 14 consists of various fountains and rollers necessary forthis class of printing machines and is attachedto a separate frame 15.This frame has truck rollers 16 which travel over rails 17 which latterare stationary on the bed plate 18 which also forms the bed plate forthe main frame 1. Two lines of rack-gearing 19 are also attached to thebed plate 18 and into which gear the wheels 100 which latter areconnected by the transverse shaft 20. One of the gear wheels 100 isdriven by means of the pinion 101 which latter can be operated by meansof a handscrank 21 and by means of this series of gearing, the frame 15and the therewith connected inking mechanism 14 is caused to travellongitudinally over the rails 17 whereby the frame 15 can, at the willof the operator, be brought nearer to or farther from the main frame 1.The object of this construction is to permit an easy access to theinking mechansm and to the formcylinder. The frame 15 can be locked tothe frame 1 as seen in Fig. 2 of the drawings by means of draw-bolts 22which ass through a pair of lugs 23, one of which is part of either ofthe frames, or by means of any other suitable locking mechanlsm.

The forni-cylinder 2, as shown in the various views of the drawings, isintended for the transference of eight diHerent tints or colors and isserved by means of an inking mechanism consisting of eight differentsets of inking rollers, fountains etc. and for the sake of illustrationthe following series of colors are intended to be used in connectiontherewith, namely, inking rollers 24 Supply a light yellow color, inkingrollers 25 a dark yellow, rollers 2G light red, rollers 27-dark red,rollers 28 light blue, rollers 29 dark blue, rollers 30 gray, androllers 31 a brown color. These sets of rollers are placed radially tothe axis of the form-cylinder, and as illustrated in detail in Figs. 2,4 and 5 of the drawings, each consists of the usual fountain 32, ducker33, distributing inking cylinder 34, riders 35 and form-rollers 36. Theshafts 37 of the distributing inking cylinders 34 are placed in radialslots 38 in the frame 15 and extend outwardly of the same. The shafts3S) of the riders and the shafts 40 of the form-rollers are placed inrunways 41 arranged radially to thc axis of the forni cylinder 2, andboth ends of all the shafts 40 are provided with groovcd contact rollers141 which in turn travel over the periphery of multiple grooved guiderollers 42 which latter are fastened to the ends of the forni cylinder 2and rotate with the same for the purpose hereinafter more fullydescribed.

In order to keep all inlring rollers concenA tric to the outer periphervof the form-cylinder, the projecting ends of the shaft 37 of the variousdistributil'ig inking cylinders, which project outwardly of the frame 15as described above, are encircled by a semicircular band 43 as seen inFig. 1 of the drawings. This band 43, midway is supported at 44, andlikewise with its ends 45 on the frame 15 and can be placed in properoperative position by means of set-screws 46 which will permit atightening and loosening of all inking rollers by drawing thesemi-circular band 43 toward or away from the vertical joint between theframes 1 and 15. The upper four inlring sets 24, 25, 2G and 27 willgravitate toward the center of the form-cylinder, while the lower fourinking sets 28, 29, 3() and 31 are adjustable toward the form-cylinder 2by means of special set-screws 47 which pass through the band 43 andbear upon the projecting shafts of these sets. The set-screws 47 may bedis pensed with and a compressing spring 48 centrally located at thesupporting point 44 may be employed to force the band. 43 and the inkingrollers inwardly toward the forni roller.

The circumference of the form-cylinder 2 is divided into as manysections, eight in this case, as there are inking sets, each sectionbeing designed to carry one segment forni and each form is designed toreceive its respective color from one of the inking sets and afterwardto transfer the color to a respective section of the transfer cylinder3. This cylinder 2 is preferably composed of end spiders 49 having a hub50 and outer circumferential bearing ring 51, or one or more additionalspiders centrally located between the end spiders may be employed incases of exceptional width of the printing press. Mounted on the outerperiphery of the bearing ring 51 are the eight segment forms 52, 53, 54,55, 56, 57, 58 and 59 with a longitudinal open space 66 left betweeneach two adjoinin segment forms, it being understood that t e peri herallengths of each segment form as we l as its transverse width from end toend are the respective dimensions of the sheet which is 'to receive thedifferent impressions thereon. As seen in Figs. 4 and 5 each segmentform has inwardly extending transverse lugs 60 which fit in accuratelyspaced recesses (51 cut into the outer cireuniference of the bearingring 51. Set-screws ('12 placed in the bearing ring 51 will permitradial adjustment of either end while locking set-screws ($3 areelnployed to facilitate transverse adjustment and also to securelyfasten th(` segment forms into position.

ln order to attach the form plate (511 which contains the subject matterthat is to be transferred and to be printed in the various colors on thesegment forms 52 to 5S) inclusive, adjusting follower plates (i5 areintroduced into thc open spaces (3G between the adjoining forms. Theseplates are provided with a row of buttons G7 to which the forni plate G4can be attached, and a number of set-screws G3 which bear against therigid sides that form thc recess (it) will force the follower plate G5and the therewith connected form plate G5 outwardly and thereby tightenand rigidly secure the same. Projecting lugs G9 of the bearing ring 51and fitted in the corresponding recesses 7() of the follower plate (35hold the latter in its posi tion and prevent radial dislodgment of thesaine.

As seen in Figs. 3 and 5 of the drawings, each end of the form-cylinder2 has rigidly fastened thereto by bolts or rivets 71, and concentricallyplaced to the axis of the shaft 7, a guide roller 42 as above referredto. Each of the guide rollers 42 is provided with a plurality ofcircumferential ridges 72 and intervening grooves 73, the number of saidridges on each guide roller corresponds with the number of the sets ofcontact rollers 141 which latter are mounted on the shafts 40 of theforni-rollers 36. Three of said contact rollers 141 form a` set and eachset occupies one of the circumferential ridges 72 of the guide roller 42on either side of the for1ncylinder 2, and upon rotation of the latterthe contact rollers 141 will rotate upon their own axis, being held infrictional Contact with the guide rollers as above described by means ofthe encircling band 43 and thc therewith connected set screws 47. Eachone of the circumferential ridges 72 of the guide rollers 42, asillustrated in Figs. 2, 3 and 4, has at 74 a slight segmental depressionwhich is concentrlc to the outer periphery of the same and the length ofthe are of each of said depressions 74 is equal to the length of the arcof each of the forms 52 to 59 inclusive plus the length of the arc ofone of the recesses 66. The radial distances of the ridges 72 and thatof the depression 74 are so arranged that the ridges 72 will cause thecontact rollers 141 and the therewith connected form-rollers 36 totravel slightly above the outer surface of the form plate 64 attached tothe form-cylinder 2, but when the contact rollers 41 travel over thedepressed path which coincides with the surface of the respective formplates, the latter will, during the travel over this dcpressed path,become subjected to the inking action of the form rollers 24 to 31inclusive. It will thus be seen that during one revolution of theform-cylinder 72 all the inking attachments with their form rollers willsuccessively be set in operation and that the form plates attached t:the segment form 52 can receive the color only from the inkingattaclnnent 24, that of 53 from 25, and etc. As shown in Fig. 2 olf thedrawings the inking attachment 24 is in the act of traveling over theform plate attached to the form 52, while all the other inkingattachments which are out of action will be held in suspension abovetheir form plates by reason of the contact rollers 141 riding on thehigher ridges 73 ot' the guide rollers 42.

The transfer cylinder 3 is of the usual construction and is subdividedinto eight parts respectively numbered 75, 70, 77 to 82, correspondingto the eight subdivisions of the form-cylinder 2, and is of equaldiameter thereto, each of the subdivisions is properly rubber blanketedand is adapted to receive the transferring impressions from the formplates of the form-cylinder 2 when revolving in opposite directions tothe latter.

A paper Vcylinder 4 has been introduced which is of novel constructionand which is designed to receive upon the sheets of paper carriedforwardly by the same, the various color impressions brought thereto bythe transfer cylinder 3. The circumference of the paper cylinder 4 isproportionate to the form-cylinder and to the transfer cylinder as isn-l-l to a, namely, its circumference possesses one segmental surfacemore than that of the form-cylinder, and in this ease has nine segmentsnumbered on the drawings 83 to 91, and each two adjoining segments haveone intervening open space 92 equal to that of the open space 66 of theform-cylinder 2 and that of the open space 93 of the transfer' cylinder3, and it becomes apparent that in revolving the three cylinders in thedirection of the arrows as seen in Fig. 2 of the drawings the segmentsurfaces will be brought into and out of contact at the same time, andthat between cylinders 2 and 3 always the same surfaces will meet, butthat between cylinders 3 and 4 successively alternating segment surfacesof the paper cylinder 4 will come in contact with the segment surfacesof the transfer cylinder 3. The recesses 92 are provided with grippingattachments 94 of 'any a proved construction. The paper roll 5, t epaper tension 6, the rotary cutter 95, the releasing grip 96 and thetake-olf 97 are of any of the old approved forms and are notspecifically claimed herein.

The fountain 98 with metal roller 99 and distributing roller 102, thelatter covered with mole skin, introduced as seen in Fig. 2. ol' thedrawings, and the object` thereof is to subject the printed sheets, whenthey have arrived at this point of their travel around the axis oli' thepaper cylinder 4, to the action of a` neutralizing solution which latterhas the tendency to rapidly dry the last color imparted to the sheet andto place the same in condition Isuitable to receive the next succeedingcolor impression. The action and operation of this cylinder is aslollo\rs;'l `he gripping attaehnient 94 takes hold ot' the sheit ofpaper 103, just cut in the proper length by the rotary cutter 95, andthe sheet will attach itself in the forward movement of the cylinder 4to the segment 91 and will receive its tirst color impressionH-lightyellow-as soon as it comes in contact with the segment T9 oi thetransfer cylinder rl`he prior sheet resting on the segment 83 iscommencing to receive the last color impression-brown-fro1n transfersegment 80 and will become detached therefrom when it arrives at thetake-ott' 90, the last finished printed sheet having become detachedprior to this from the segment 90 which as shown in Fig. 2 of thedrawing is waiting the reception of a new sheet, with the grippingattachment 104 open, as soon as the latter arrives in the position nowoccupied by the grip 94. The sheet on segment 84 on its seventhrevolution around the cylinder 4 has just received the seventh colorimpression-graythe sheet on segment 85, on its sixth revolution aroundthe cylinder 4 has lately linished receiving the sixth colorimpression-dark blue-and so on. Each one of the sheets of paper makeseight revolutions around the shaft 11 and during each of saidrevolutions receives one of the sequence of colors and is each' time,and when arriving at the neutralizing bath roller 102, subjected to thelatter`s drying action.

The machinery necessary to operate the gripping and releasing attachmentfor the sheets is not shown in the drawings and any of the well knowndevices suitable to accomplish this obj ect may be employed.

From the foregoing description it will be seen that the functions of thevarious cylinders and their adjuncts are positive and accurate in theiraction and that the object of the invention, namely, to provide a.simplified and accurate multiple color printing press with positiveoperation and of easy adjustment in all its component parts is therebyattained.

It becomes apparent that the cylinders or printing presses of this kindcan be provided with any number of segment forms and a correspondingnumber of inking attachments, and that the number of segment forms onthe paper cylinder must equal that number plus one additional segmentform.

It. will also be apparent that the 4Style of the eylindera designated aspaper cylinders in the foregoing epeeilieation can be applied to anyother class of multipleprinting in avlnnel provided that such cylinderis en'- (flnn'lerentially `subdivided insegmental parte whirh in numberexceed by one the i'orni and transfer cylinders, :segmental enbdivisions, and where eueh subdivieionel on the paper cylinder or itsequivalent eoineide in .enriaee extent with the Surface extent oi' thesubdivisione of the forni and transfer cylinders, and is also equal tothe latters perpberal speed.

The class of multiple printing machinery to which my System ofmultipleeolor printing can be applied embraces those used for dry plateprinting, surface printing, either from plate or stone, textile printingor any other class of printing known to the graphie arte when used forColor printing.

Having fully deferibed my invention, what I elaiin as new and desire toSecure by Letters Patent, ie;-

In a niultiple-e0lor printing machine, a paper cylinder having segmentalSurface Subdivieionel with interveninr open s aces which containgripping attac inients a apted to reeeive and hold the sheets ofmaterial designed to be printed upon and placed on said segmental.Surface subdivisions, means for feeding the paper or other material insheeta from a eontinuone paper or material roll to the paper eylii'ider,a sul'ipleinental roller placed so as to eon'ie in surface contat-t witheach ol the printed sheets attached to the paper Cylinder a reeervoirfor supplying nentri'tlizing and dryiiig solution to said supplementalroller, whereby the sheets of the paper are Subjeeted to the action ofthe neutralizing and drying Solution before receiving a Second eolorimprint7 Substantially as described.

In testimony that I elaiin the foregoing as my invention I have Signediny name in preeenee of the subscribing Witnesses chie 18th day of .lune1906.
